METHOD TO PRODUCE PALLADIUM CATALYST OF HYDROGEN FINE CLEARING FROM OXYGEN Russian patent published in 1995 - IPC

FIELD: hydrogen fine clearance. SUBSTANCE: palladium catalyst is produced by palladium uniform distribution on surface of aluminum gamma oxide with pores volume with radius 100 1000 no less than 50 Reduction of the precious metal is achieved due to circulation impregnation by palladium acetate solution at speed of 25 -50 h^-1 during introduction of active component in circulating solution within 0.5 1.0 hour and impregnation duration of 2 5 hours with following drying and reduction in stream of hydrogen under temperature of 250 300 C. This increases effectiveness of hydrogen clearing and decreases palladium losses in process of its production by losses-free technology. EFFECT: increased effectiveness of hydrogen clearing, decreased losses of palladium. 6 cl, 1 tbl
